ABSTRACT:
A method and a device for measuring the inner diameter dimension of a work capable of easily and accurately measuring the inner diameter dimension of the work with a simple structure; the method, comprising the steps of feeding compressed air to the inner peripheral part of a master with a known inner diameter dimension to detect a back pressure, calculating back pressure characteristics showing a relation between the inner diameter dimension and the back pressure from the measured result, feeding compressed air to the inner peripheral part of the work based to be measured to detect a back pressure, and measuring the inner diameter characteristics, whereby the inner diameter dimension of the work can be measured without rotating the work.
